EPO, short for Erythropoietin, is a critical glycoprotein hormone primarily produced by kidney tissues in the human body. It serves as a master regulator of erythropoiesis, the biological process responsible for red blood cell generation in bone marrow. For laboratory research, our EPO is recombinantly manufactured using eukaryotic expression systems, which enables correct post-translational glycosylation, a key structural feature that maintains its native biological activity, unlike synthetic peptides without glycosylation modification.

The core biological function of EPO centers on binding to specific EPO receptors located on erythroid progenitor cells within bone marrow. After receptor binding, it triggers intracellular signaling cascades that promote progenitor cell proliferation, differentiation and survival, stimulating the production and maturation of red blood cells. This pathway makes EPO an essential research reagent for hematology studies, exploring mechanisms of anemia, hypoxia response and oxygen homeostasis. Preclinical research also expands into non-hematopoietic effects; multiple lab studies have investigated EPO’s neuroprotective, tissue-protective and anti-apoptotic properties under hypoxic or oxidative injury models.

Our recombinant EPO undergoes rigorous downstream purification processes, including affinity chromatography, ion exchange chromatography and ultrafiltration concentration to remove host cell proteins, DNA residuals and other impurities. Each batch is fully tested for purity, biological activity, endotoxin level and molecular identity. Complete COA, SDS-PAGE reports and activity assay data can be supplied for every batch to satisfy academic and biotech lab quality documentation standards. The product is lyophilized to stabilize the protein structure, greatly reducing protein denaturation and degradation risk during shipment and long-term frozen storage. It is widely supplied to university laboratories, pharmaceutical R&D institutes and life science research teams for cell culture, hematopoietic differentiation experiments, hypoxia pathway research, tissue injury and apoptosis related preclinical studies.
